Widget Walkthrough YouTube - Touchwiz 3.0 walkthrough with the Samsung Captivate (Galaxy S) TouchWiz 3 is fantastic because it consists of some widgets, different (better IMO) color scheme, WiFi/BT/Silent/Vibrate switcher in notifications, and the launcher. The best part about the launcher? It can be replaced. I'm not a fan of "heavy" UI overlays (ie. HTC Sense) at all. I think TouchWiz does enough without doing too much.
